Frequently Asked Questions

What is a 980nm High Power In-line Optical Isolator?
A 980nm High Power In-line Optical Isolator is an optical device designed to transmit light in one direction while blocking light in the reverse direction. This prevents unwanted feedback and reflected light from entering sensitive components like fiber lasers and amplifiers, ensuring stable and reliable operation.
What are the key features of the DK Photonics 980nm High Power Optical Isolator?
The DK Photonics 980nm High Power Optical Isolator offers low insertion loss, high isolation, high power handling (customizable up to 50W), excellent temperature stability, high reliability, and is available in both polarization-maintaining (PM) and non-PM versions. Custom fiber types and configurations are also available.
What applications are suitable for the 980nm High Power In-line Optical Isolator?
This isolator is ideal for high power fiber lasers, high power fiber amplifiers, instrumentation, test and measurement setups, and fiber amplifier laboratory research. Its high isolation and power handling make it suitable for demanding optical systems.
Can the DK Photonics 980nm isolator be customized for specific requirements?
Yes, DK Photonics offers customization for fiber type, power handling (5W, 10W, 20W, 30W, 50W), wavelength, and package configuration. Custom fiber pigtails and other specific needs can be addressed upon request.
What is the difference between PM and non-PM types of the 980nm optical isolator?
PM (Polarization-Maintaining) isolators maintain the polarization state of the transmitted light, which is critical for certain applications like coherent communications and high-precision measurements. Non-PM isolators do not preserve polarization and are suitable for general applications where polarization is not a concern.
How does the DK Photonics 980nm isolator handle high power levels?
The isolator is designed with advanced materials and construction to handle continuous wave (CW) or pulsed optical powers up to 50W (customizable). For higher power applications, fiber splicing is recommended instead of connectors to ensure optimal performance and safety.
How do I order or request a quote for a custom 980nm High Power Optical Isolator?
To order or request a quote, provide the correct part number (P/N) and specify your requirements such as fiber type, power handling, wavelength, and any special configurations. You can contact DK Photonics via their website, email (sales@dkphotonics.com), or phone for assistance.
